• A. (A) - (iii), (B) -(iv) , (C) - (ii) , (D)- (i)
• B. (A)- (v), (B) -(iv), (C) -(ii) , (D) -(i)
• C. (A)- (iii), (B) -(iv), (C) -(i) , (D) -(ii)
• D. (A)-(i),(B)-(ii),(C)-(iii),(D)-(iv)

Answer 1

The correct option is B (A)- (v), (B) -(iv), (C) -(ii) , (D) -(i)

A) Abrin	Abrin is a natural poison that is found in the seeds of a plant called the rosary pea or jequirity pea. Abrin is similar to ricin, a toxin that also is found in the seeds of a plant (the castor bean plant). So the correct option is 'toxin'
(B) GLUT-4	Glucose transporter type 4, also known as solute carrier family 2, facilitated glucose transporter member 4, is a protein encoded, in humans, by the SLC2A4 gene. GLUT4 is the insulin-regulated glucose transporter found primarily in adipose tissues and striated muscle. So the correct option is 'enables glucose transport into cells'.
(C) Collagen	Collagen is the main structural protein in the extracellular space in the various connective tissues in the body. As the main component of connective tissue, it is the most abundant protein in mammals, making 25% to 35% of the whole-body protein content. So the correct option is 'intercellular ground tissue'.
(D) Cancanvalin	Concanavalin A (Con A) is a plant lectin that is purified from jack beans. Con A binds to the mannose residues of various glycoproteins and activates lymphocytes. So the correct option is 'lectin'.
